Bolt-on Hanger Spacing for Slipper Spring # SP-178275

Question

Question:

Im rebuilding my old boat trailer with SP-178275 slipper springs and the bolt-on hangers CE14016G and CE14017G. Should the center-to-center distance between the front and rear hangers for these springs be 22.75 inches? The B dimension in the length table. Thanks.

Yes, the B measurement of the slipper spring part # SP-178275 that you referenced is the correct hanger spacing to use. This puts the spring right where it needs to be on the rear hanger.
